摘要:
A method of testing multiple fluid samples with multiple biopolymer arrays. A cover is assembled to a contiguous substrate carrying on a first side, multiple arrays each with multiple regions of biopolymers linked to the substrate, such that the cover and the substrate together form a plurality of chambers each containing a biopolymer array and each being accessible through its own port. Multiple fluid samples are introduced into respective chambers through a port of each such that the fluid samples contact respective arrays. A binding pattern of the arrays is observed. An apparatus and kit useful in such methods, are also provided.

Systems and methods for optimizing polymer analysis are provided. One such system includes a polymer analysis system having a polymer control system. The polymer analysis system is operative to: apply a set of conditions to a sample being analyzed by the polymer array, the set of conditions correspond to at least one characteristic of the polymer array; analyze the at least one characteristic using the polymer control system; and generate polymer array data.
摘要:
A method of using a chemical array unit having a chemical array with probes at multiple feature locations. A request for test may be read, which test uses a sub-array of the array. A pattern of the sub-array may be retrieved from a memory using the test request, which memory carries a pattern for the sub-array which is retrievable with the different test request. Also, a method of reading a chemical array unit which has been exposed to a sample, and feature locations of which have been rendered incapable of providing signal data representative of binding of a sample component. Further methods, apparatus, and computer program products are provided.

Apparatus and methods for mixing fluids are disclosed. An apparatus comprises a housing or channel having an interior with capillary dimensions and a pressure activated mechanism in fluid communication with the interior. The pressure activated mechanism is activatable to cause motion of fluid in the interior of the housing thereby mixing the fluid in the interior. An apparatus may comprise an activating mechanism for activating the pressure activated mechanism. Typically, at least a portion of the interior of the housing comprises a linear array of features for conducting chemical reactions. Optionally, an apparatus comprises a fluid dispensing device.

摘要:
Methods and compositions are provided for producing arrays of polymeric binding agents. In the subject methods, the individual polymers of the array are synthesized using solid phase synthesis techniques on the surface of a substrate. A critical feature of the invention is that one or more locations on the substrate surface are spatially and temporally protected by a protective bubble during the synthesis protocol, where the protective bubble may be produced using any convenient bubble producing means. The bubble producing means may be a component of either a substrate or a structure separate from the substrate. Also provided are the arrays produced by the subject methods, kits for use in practicing the subject methods, and methods of using the arrays in analyte detection assays, including hybridization assays, such as gene discovery, differential gene expression and gene sequencing assays.
摘要:
An apparatus for mixing fluids comprises a housing having at least a portion of its interior, for example, a channel, with capillary dimensions and at least one structural member in the interior adjacent an end of the channel. The dimensions of and placement of the structural member are sufficient such that intermittent application of centrifugal force to the interior of the housing causes movement of the fluid therein. The housing may comprise a mixing chamber or area that is in fluid communication with the interior. The apparatus may comprise a mechanism adapted to generate centrifugal force within the housing to cause movement of fluid in the interior of the housing without exit of fluid therefrom.
